Quarter Wave VS Half Wave Verticals (#1388)

Ed, K6SDW, currently has a quarter wave vertical antenna established but has an opportunity to setup another antenna. In a restricted space, will a quarter wave vertical with radials perform better than a half wave vertical with a small counterpoise or vise versa?

Antenna Modeling for Beginners – Inverted-V Dipole (Part2)

Post author By admin
Post date March 9, 2026

Antenna Modeling for Beginners - Inverted-V Dipole (Part2)

In this episode we take the flat-top dipole from Part 1 and convert it into an inverted-V antenna using the drawing tools in MMANA-GAL. This short practical tutorial shows how to modify antenna geometry and understand how shape affects radiation patterns.

In this video we:

• Use the wire drawing editor
• Split a dipole into two wires
• Convert a flat dipole into an inverted-V
• Adjust antenna height above ground
• Check SWR and resonance
• Use the Wire Scale function to retune the antenna
• Compare the far-field radiation pattern

You’ll also see why modelling sometimes shows odd impedance values when elements are very close to ground, and why that doesn’t necessarily mean the antenna won’t work in practice.

Model files used in this series

All MMANA-GAL antenna models used in these tutorials can be downloaded here:

This folder will be updated as new videos in the series are released.

The Contraption | Turn Your QMX Into An HF HT!

The Contraption | Turn Your QMX Into An HF HT!

The Contraption by @HamRadioDuo was something I saw a couple months ago and became slightly obsessed with. It’s a 3D printed design that houses your QMX, QDX, or QCX and incorporates an internal battery power bank and their Just OK Mini antenna as well as magnates on each side for mounting a CW key and cell phone. The only problem is they made it for a slightly different battery bank. That’s were my obsession really went down the rabbit hole. I had to learn how to modify the file in Bambu Studio to widen all 3 parts by 1mm to fit my battery. Would you believe it actually worked, after many prototypes. This is the story and build of this absolutely ridiculous Contraption.
⭐️⭐UPDATE: Both versions of The Contraption are now up at https://hamradioduo.com/the-contraption-3d-files-available-for-the-preview-version/ for you to download whichever version of battery you have. Scroll down for the K8MRD Redux Version if you have the same battery https://amzn.to/4ldxfhr as me.

Holly Farm Work Party – Help Needed

Post author By admin
Post date March 8, 2026

Holly Farm Work Party - Help Needed

Over the last couple of years I’ve been quietly building up the antenna field here at Holly Farm – towers (well… masts), verticals, phased arrays, four-squares and various receive antennas. This spring I could do with a bit of help finishing a few practical jobs, so I’m organising a couple of Sunday work parties. Nothing complicated, just some good old-fashioned radio engineering in the field.

Jobs planned:

• Laying two Beverage-on-Ground receive antennas (VK/Japan & North America)
• Burying LDF4-50 Heliax runs from the shack across the field
• Tidying the tree line and trimming overhanging branches

If you’re within driving distance and fancy helping out for a few hours, fill out the interest form below so I can coordinate dates and numbers.

👉 Volunteer Form:
https://docs.google.com/forms/d/e/1FAIpQLSckcAraHP2dhzpa7uFJXKcs3QTwCvDZjgUs1MpCjNqUnAvdKA/viewform?usp=dialog

Typical plan will be 10am – 2/3pm on a Sunday.

Bring gloves, boots, and if you have one, a spade or shovel. It should be a relaxed day – a bit of digging, a bit of antenna chat, and probably a lot of radio talk.

I’ll also be filming parts of the work for future videos.

Later this year I’m hoping to start a monthly Shack Night at Holly Farm as well – more on that in another video.

Enjoy your radio.
